Abstract Scope |
Novel nanocomposites are in high demand in various industries. Namely automotive and aerospace sectors where they are commonly used as adhesives and coatings. They demonstrate unique physical and chemical properties, such as high strength-to-weight ratio, excellent chemical, and corrosion resistance. Noble metallic plasmonic nanoparticles have been integrated into epoxy systems in recent years owing to their outstanding optical properties. Spiky gold nanoparticles (SAuNPs) with localized surface plasmon resonance (LSPR) of up to 1320 nm were successfully synthesized and integrated into a thermoset resin system. Transmission electron microscopy (TEM) and UV-Vis-NIR confirmed the size, morphology, and absorbance peak of the SAuNPs. The curing behavior of the nanocomposite is herein reported. Non-isothermal differential scanning calorimetry (DSC) scans of SAuNPs-epoxy systems suggest that SAuNPs facilitated the exothermic reactions of epoxy resins. |
